Everything You Need To Know About Supply Lines

[@TheWpaman]

Tony I've been working on my own rental properties for twenty years and I want to mention that when I find a chrome plated copper line I usually leave it in there. I can't remember one failing ever. I have had a couple of stainless steel braided supply lines burst during that period of time and was lucky to either have it happen in a place that did not cause damage or have a quick thinking tenant (which in and of itself is a miracle) who shut the valve quickly. My advice would be to replace the s steel braided lines at least every seven years. Eventually they will leak and maybe burst.

[@masterflowplumbing9812]

You are correct. Well sort of. A good braided line will never burst or fail. Unfortunately most in the market will only last about 7-10 years then it will harden and lose its elasticity. The good ones also come with metal ends. I never trust a plastic nut made in china to not break at some point and cause a flood. With all that said. My channel is geared toward the plumbing novice or beginner. Braided lines are so easy and caveman can do it. Chrome plated brass lines while are best (your right). They are also the most difficult to get right. Most will fail at them. Thanks for watching.

Thanks, this video is exactly what I was looking for. A clear explanation. Sorta rare. Well done.

Thanks. A good video to ensure I connected the braided supply lines for for my new basement utility sink correctly to the supply lines and valve fittings I had a contractor plumb in for that sink.

Glad to help. Thanks for watching

It's my first time replacing the flushing system and the toilet water supply hose. It looked easy from watching KZbin videos but I struggled with old parts and marrying old with new. By watching your video, ideas sparked. Thank you.

[@masterflowplumbing9812]

Your welcome

[@artfquinn]

Thanks so much. You are the best. All other KZbin plumbers only demonstrate with the new thread supply line. They don't deal with the past. I have an old house. The supply lines don't look like those new thread ones. So I was so confused.

Hi Tony. I have a kitchen faucet that has those Cooper Standard Automotive brand quick connect snap fit supply lines serving the several small faucet fittings. One end broke off a line and I am trying to figure out how to replace the line to get the kitchen sink functional. Those lines are real neat but nowhere to be found.

[@masterflowplumbing9812]

You won’t find them. They are brand proprietary

[@aseelsaeidi1587]

I have a quick question that I hope you can help with what size plug should I use for a 7/8 female water pipe? I really need to find the right one to close it effectively. Your assistance would be greatly appreciated!

[@masterflowplumbing9812]

I’m going to guess you’re loooking for a 3/4 inch pipe plug.

[@lauramcshane2562]

How tight do you have to get the newer metal braided lines with compression fitting? I read it's just a quarter turn past hand tight but I don't think that is true because I still have a small leak coming from the 3/8ths connection that attaches directly to the hot supply shut off valve. I don't want to crank down on it more without asking. It's tight but I could still turn the nut more if need be. I don't want to cause another bigger leak if I can help it. And these don't require plumbers tape either correct?

[@masterflowplumbing9812]

Snug is tight enough. Broke is too tight.its also possible you have a bad fitting

[@timregello6032]

Tony, should teflon tape be used on the threads for the braided steel supply line connections?

[@masterflowplumbing9812]

No.

[@Rae_Mah_Boo]

And these sink hoses, plastic/metal, interchangeable? For example, could I replace my plastic pex with the metal one?

[@masterflowplumbing9812]

As long as the two ends match up then yes. It should be pretty easy to do

[@RichardSinek]

Great information but where can I get one of those extenders you talked about around the 9 minute mark? I got a laundry sink and faucet with built in hoses - like a kitchen faucet but they are about 3-4" too short. I can't find extenders at hardware or big box stores and the ones on Amazon have 3/8 on one end but M10 on the other...... I have not found 3/8M to 3/8F.

[@masterflowplumbing9812]

Here ya go. Thanks for watching. Just discard the compression nut and ferrul that comes with it. amzn.to/3SbVrUn

[@RichardSinek]

@@masterflowplumbing9812 Thank you so much!

[@ataurrahman2760]

Tony, our home was built in the late 1990s and the builder had used Supply line which is about the diameter of a pencil, some sort of very hard but flexible plastic material. Anyway, one of the faucet shutoff valve went bad and I took the Supply Line to Hardware store and they said you need to change these lines in your entire home 'cause the chlorine in the water corrodes them and disaster is just waiting to happen. Is this correct? They withstood well over two decades without any issue though.

[@masterflowplumbing9812]

Seems far fetched. Chlorines at that level would be irritating to humans also

[@bluearcherx]

supply line 201: i have a vintage 1930s bathroom, I want to use 3/8 OD chrome plated copper risers for the aesthetic. obviously compression fitting at the stop, but I am not sure what kind to get for 1/2" NPS faucet connection.. straight threads. Do I just get a bullnose for this and tighten it down w/o tape or sealant?

[@masterflowplumbing9812]

The old school bullnose did not require any sealant such as tape or dope

[@bingojamas4786]

Hello. My new Delta kitchen faucet has PEX lines directly attached to the fixture. On the supply side, the PEX tubes have a nut and a red (hot side) and blue (cold) plastic fitting with a rubber washer pressed into the end. The hardware pack has two of those directional plastic rings you described. Do I use those rings only if I cut the PEX to shorten it? In other words, use the pre-installed Delta fitting as is or the plastic ring and nut if I cut it. Hope this is clear. Thanks

[@masterflowplumbing9812]

Yes if you need to shorten the lines that’s why they give the extras. I usually bend or curl those delta lines and use the factory connections. Thanks for watching.

[@bingojamas4786]

​@@masterflowplumbing9812 Thank you for the timely reply. Per your advise, I was able to carefully loop the lines into position. I have never used PEX before, and I don't know how tightly it can be bent before it kinks. I appreciate the help.

[@independentthursday]

Don’t try to cut the supply lines on Delta faucets even if installation instruction says you can. Ran into the issue when shortened supply lines bursted and Delta’s customer support said that if you trim the supply lines according to the manual - you alter the product, hence voiding the warranty.

[@ufosrule]

If I can't disconnect a line under the bathroom sink valve because of corrosion, are there 1/2 inch to 1/2 inch extender supply lines available that don't require compression-to-compression connection fittings? Specifically, I need an extender to connect to an existing 1/2 inch connection, the 3/8 is already connected to the valve I don't want to remove either the old valve or the line. Hope this makes sense.

[@masterflowplumbing9812]

Thanks for watching. No there is no way to extend without the compression connection. That’s what type of connection is at the shut off valve

[@lilFougie]

My cold supply line to my kitchen faucet doesn't have a rotating nut on the shutoff valve side. Is there a way to reconnect it with another fitting without replacing the whole line? I'm installing an RO water filtration system and I had to disconnect that supply line to add the feed water adapter under it. Thanks! Edit: it rotates like new, after eventually being freed.

[@masterflowplumbing9812]

Tough to determine without seeing. Probably should call a plumber in your area

[@lilFougie]

@@masterflowplumbing9812 two wrenches freed it eventually. Not sure what helped most, I was just worried I would break/deform the line when I first tried wrenching it. They are all probably designed to rotate, since their conception.

[@sisiguess5750]

I need to install exposed brass supply lines with bullnose ending, the problem is the faucet connection is a female 10M ending the manufacturer supplied flex line but I can’t use them since the sink is free standing console. Please any suggestion about adapters will be appreciated.I am stuck with no sink. Tanks

[@masterflowplumbing9812]

Check on Amazon or your local suppliers. Sometimes eBay has odd stuff.

[@BillPollackMusic]

Big help, thanks!

Thank you for watching

[@martylynchian8628]

Sup my dude, how do I connect a water feedline from a sink to something I can used for a garden or drip irrigation setup?

[@masterflowplumbing9812]

You won’t get enough water for irrigation from a faucet supply. You need a 3/4-1” supply line with a proper back flow device installed.you should probs hire a pro for that job. Thanks for watching.

[@RussellHartman-n3x]

Question for you: what do you do if you have a braided faucet line that is (I believe) in mm, not standard? Do they sell conversions?

[@masterflowplumbing9812]

I’ve never had that be a problem. I’ve never heard plumbing pipe measured in metric. But I am in the United States

[@Gshev1288]

I would like to switch hot and cold connections to my kitchen faucet, as the side handle for the hot water is pointing up and water is dripping from wet hand on the countertop. Is there any difference in pipe connectors between cold and hot ? Can faucet cartridge handle such switch-over?

[@masterflowplumbing9812]

Hot and cold connections are the same in most cases Thanks for watching here is a link amzn.to/4acbGYv

[@BrianHorton1]

If my supply line is 3/4”, can I transition to a 1” and get the benefit of additional flow, or am I stuck with 3/4” max all the way through?

[@masterflowplumbing9812]

Increasing size usually leads to less psi. . Decreasing increases psi.

[@martinmercerjr8615]

My question is, I am not sure if they are making them cheaper, nowadays every time I change the faucet and a toilet, I end up changing the supply line. Today I changed my faucet and supply line would not stop leaking. So I went to buy a new and it stopped leaking. I don’t get it?

[@masterflowplumbing9812]

Supply lines form a groove in the bull nose ends. Switching faucets can misalign the original wear groove. I always use new supply lines when I change a faucet or toilet. Thanks for watching

[@tomonentrepreneurship]

The only braided line used in my house failed and flooded. I'd never use it again. There are lots of others who have had similar experiences. You can find other videos here on KZbin with the same experience.

[@masterflowplumbing9812]

Yeah there are some crappy braided supply lines. I won’t use anything with plastic nuts . These are common at the big box stores and yeah I’ve seen many that have failed. The braided lines I use have metal nuts top and bottom. They really are fool proof.

[@tomonentrepreneurship]

This is metal top and bottom. It completely blew out. @@masterflowplumbing9812

[@rickwilson478]

​@masterflowplumbing9812 can you share with us what brand of braided supply lines you use and if you have to buy them at plumbing supply houses or if they are available at Ace, Lowes, Home Depot?

[@upshiftgo]

I just installed a new dishwasher with a new steel braided hose and immediately after our sink tap water started to taste like a new hose. Are there hoses that don’t have such a bad taste when new like typical hot water sink hoses?

[@masterflowplumbing9812]

Chinese made products suck

[@upshiftgo]

@@masterflowplumbing9812 I picked up a new hose. Hope it’s not made in China. Let me look… Dammit, it’s made in China…

[@danielr8407]

Im trying to add an under the seat bedet addition to my toilet, but the original water supply line was the chromed shaped to fit line. I need to replace it with a flexible hose to get the bedet setup installed, but the new hose wont thread on to the old shut off valve because of the brass insert in the flex hose. Is there an adapter to fix this problem? Im familiar with wrenching on just about anything, but not much plumbing experience. I know the original chrome supply line had a flared end on the tubing that the nut is attached to that just seats onto the valve when the nut is tightened down. Was hoping there was a fix for this without having to replace the shut off valve with a modern style one. I couldn't find anything at my local home depot that would work and im not to informed with all the proper names of these parts to find anything online.

[@masterflowplumbing9812]

Depending on sizes yes. Here is a link to one for 3/8 which is most common amzn.to/3TOM7qq

[@mgomez5606]

Can the black seal on the steel braided hoses be replaced in case they leak?

[@masterflowplumbing9812]

Even if you could you probably shouldn’t

[@mgomez5606]

@masterflowplumbing9812 I was just wondering if they could be changed if connection leaked.

[@Finn_Classics]

Can you replace the black ring inside the braided supply line?

[@masterflowplumbing9812]

I would not advise that no. Just buy a new one

[@SVwindsor]

Thankyou

[@chains6558]

Can the SS braided flexible hose be used for the shower? ( shut off valve to the shower mixer valve )

[@masterflowplumbing9812]

U can use a version of it yes. I didn’t discuss it in this video but you would want to use a full half inch inside diameter supply line for that

[@vincentpereira8416]

So are all the sink for a kitchen sink is the fitting a 3/8

[@masterflowplumbing9812]

Depends on the faucets. Most common is 1/2 female iron pipe size on faucet and 3/8 compression on the supply fitting. There are exceptions

[@mgomez5606]

I installed a toilet hose with plastic nut. I failed to keep it from twisting by not holding it with back wrench. It broke and made a mess. Lucky we were home.

[@masterflowplumbing9812]

Yeah very lucky

[@mohammedmamun6072]

Great

[@masterflowplumbing9812]

Thank you

[@zoner__]

why didn't they make the sink and toilet hoses the same?

[@masterflowplumbing9812]

Great question. In which I don’t have the answer.

[@handymanny8838]

If you could please give me some advice i would appreciate it. We live in a 30 year old trailer that is still all the old plumbing which is poly b. The kitchen faucet is needing replaced and i would like to add a shut off valve to the existing plumbing but no idea how to go about it without it looking janky. The only solution i can come up with is cutting back the poly b piping, adding a sharkbite for poly b onto the ends and im stuck on what i woild do next. Or am i just overthinking the whole thing and making it more complicated than it is

[@masterflowplumbing9812]

Mobile homes are a different animal. If a shark bite fits then buy two sharkbite stop valves. The right ones will be 3/8 compression on the one end and shark bite to fit your poly in the other end. Be sure to use the plastic stiffeners. I have a sharkbite video also so check it out. Your local plumbing supplier should be able to help. Something like this www.acehardware.com/departments/plumbing/valves/shut-off-valves/4525259

[@SuccinctOfficial]

5:27 is it called a farrow?

[@masterflowplumbing9812]

Correct. Though other terms can also be used.

[@1petrofski]

These braided lines are great to install but they make your water taste like rubber. I recently installed a faucet with a built flexi line connector and the water tastes terrible.

[@masterflowplumbing9812]

I’d be willing to bet that’s limited to a single brand. I’ve never heard of that

[@babinm]

Confused why your friend just didn’t turn off the shut off valve?

[@masterflowplumbing9812]

My friend was the general contractor on that job. He did not live there. That line held for 6-7 days before blowing apart. He simply was not there to shut off the water.

[@xVicissitudesx]
